Please note that this version is no longer maintained. If you just want to play Tetris, try Cultris II instead:


Cultris I is the predecessor of Cultris II, with gameplay leaning more towards combos. Countless records have been made and various strategies have been developed: With well over 100'000 downloads this game has become a classic! If you're nostalgic or want to try some combo-heavy action, this is the right version.

A big shoutout to Mihara-san for saving Cultris I! Thanks to his generous donation this website and the network services will live on for at least another year. Thank you 三原さん。 @miharasan!
